* "Z0 all whome'tmayeoncewi:

Be itvknown that-I Mme-(E Rm:- f mw, 'a' citizen" of United States,". and

'a, resldentof Toledo, in the county of Luc'as and State of- .Ohio, have. invented a certain newpnd' useful Tire-Tool; 'and I do' hereby "declare the foilowing'to be 'a-.full, c1ear,'a-nd exact description 'oflth invention, s uc'h as" will enable others skilled in the art to which "itappert'ains-to make and use'the same, referenc'ebeing hadto. the accompanying draw-' m .ahd usthe characters of reference marked ther'eon z -which form: apart of this s 'ecification.

invention relates to automobile acce's series, and particularly toya-tool for use in.

connection with the placingon and removal of tires from demountable rims of the split? type. -.v

The object of' my' ihvention is the provision of a simple, .eflicient and: improved ool of this character, which easily operable to. firmlyclamp the edg'es'of split de-v mountable rimsof different types and'styles and to qulCkly.COlli PS6 a 'rinito permit a tire casing to be placed on or' removed there-1 irony following specification, and while, in its The invention is fully broader -aspect,it is capable of embodiment numerous forms, a preferred embodiment thereof, is illustrated inlth'ef accompanying I drawings, in' which,- Figure 1 is a perspeetive view-"of a toolerhbodying' the inventioli 'i'n operative en-.-

thereof;- without 3 -designates a tire-casingsmounted on the" rim."}The:-rim 'i's made of spring metalto w permit a; limited contraetio'nor expansion. breaking. A tongue tfixedly rojects from one end oiv the rim at the '1 T inner side thereof. and has its free end pro:

videdvv-ithia or ofi set'i for interengagingerably inwardly ofiset relative, to the lip;

portion 6 of the hook, as bestshown in Fig. 4. Thehook 6 has its offset portion. piv'ot.-' ally connected to one .end. of an operating lever 8 bya link 9 and the hook 7 has its ofliset portion pivotallyconnected to said lever, at

- a short distance from the end th'ereof' to which thelink 9 is pivoted, through the me dium' of apairof pivotally connected links -1'0.and .11. Eachof the links. 9, 10 and 11 is pivotally connected to'the part to which it is attached. The links 9 andv l0 are carried at' the inner sides'of the shanks of'the -re- 1 spective hooks so- 'as to place them over or in substantial opposing relation-to the lip-por described in the;

tion of the respective'hookf Thelink 9 has a'rim gripping beak or jawyQ angling in; awardly from the) hook conneeting'end there of or toward the other hookpf the set whereby a inOv'mentoithe outer orlver' connect- .ingendof theilink 9 towardthe'frim will the beak 9 intogripping 'engagef swin -ment ,With the side of, the rim 1 in oppositionto the hooked-engagement of the hook!- with :the rim edge." The link 10 has a shnilarheak or jaw portionw which 'th theiinner side of the tothe' hooked engagemen is swun toward the link 9; It-will be onderstoo ,..tha t thehooks 6 and may have the lip portions thereof in grippingengagq '1s' disposed-t h e r p i in. oppositiont'of the hookl therewithwhen the'outer-end ofthe link 10 -95.

In the use of my tool are placed in hooked engagement with the rim fiangeat opposite sides. of the severed point 2 thereof, with'the hook 6 preferably placed a; greater distance from said point than the hook 7, the tool, when'first placed-in the rim, substantially Upon the application 1' ver 8 in the direction shown in Fig. 1. pressure to the lecated by the arrow in Figs. land 2, the links if) and 11 first tend-to. straighten toforce the beak or jaw 10 into gripping en 'a ement with the n u I I: O inner side of the run. When the lever 8 has been moved a su-liiclent extent to place the by reference to 9, thereby tenthlink 10 in gripping engagement with the rimthe fulcrum the outer end of the link to force the beak or jaw 9 of such lisk its gripping engagement with the rim, will be clearly understood toward the rim 2 toe drawings. Upon a continued movement of? the lever 8 after both jaws 9 and 1G 1c been placed in gripping engagement with the rim, the lever 8, links '10 and 11. and hook I will efiect inward.

When one rim end'has been moved inwardly Irom register with the other, the lever 8 will have approximately completed its lifting or in-.

Ward moving action on the hook?' so that a wfurther movement of the lever in the direcbetween the hooks 6 and 7 when first placed in engagement with a rim and the distance the hook is placed from the point oi separationil of the rim.

The feature of improvement of my tool over tools heretofore. used. resides in the capability of the tool for use in connection with rims having various shapes and styles 0f -cdge flanges, thereby requiring only onevtool for the collapsing of rims of this chair- I acter of dii'iferent styles and make.

WlS. it understood that my invention is I not limited to anyspovific constriictio'n, a r? "rangement' form parts, as. it is ca pable of HD3163? .s odilcations withoiit departing-from ape of the claims.

Having thus destiieed revenues, what stea s s as 'r' the parts endozf the lever will then =beg1n toexert eon siderable inward pressure member, whereby a movement Ur I claim as new, and desire to secure by Letters Patent, 1s,

2. -A tool of the class described having a pair of rim engaging members, an operating lever, and link connection between each of said members and the lever operable by a movement of the lever to effect relative to and fro movements of said 'members, said so link connections each having a part for grip- Pl with t e associated rim engaging member when the lever is operated in one directimii;

pair of rim engaging members, an operating lever, a link pivotally connecting one of said members to the fulcrum end oi the lever and a link pivotally connected to the other one a of sald members and having connection with said lever in'spaced relation. to .its fulcrum end,'ea ch of said links having its member carrying end provided with a jaw for gripping coaction with a rim in opposition to the respective rim engaging member when the lever is moved in one direction.

e. In a tool of the class described, a pair or run edge engaging members, an operating lever, a single link pivotally connecting oneof said members to the fulcrinn end of said 104 lever and havinga jaw at one end for gripping enga ement with the rim in conjunotion with one of said'members, and a plurality of links pivotally connecting the other of said members tosaid lever a distance from 101 its fulcruin end, one of said latter links being provided at one end with a j aw for gripping engagement with the rim in conjunctionwvith the other of said members.
